Initial Approach to Diagnosing Migraines:

• Differentiating between primary headaches (migraine, tension-type, cluster) and secondary causes (e.g., subarachnoid hemorrhage).
• The importance of patient history and reevaluation after initial treatment.
• Recognizing the unique presentation of cluster headaches and their management implications.

Effective Acute Migraine Treatments:

• First-line treatments including anti-dopaminergic medications like metoclopramide (Reglan) and prochlorperazine (Compazine), and parenteral NSAIDs like ketorolac (Toradol).
• The limited role of triptans in the ED due to side effects and less efficacy compared to anti-dopaminergics.
• The use of nerve blocks (greater occipital nerve block and sphenopalatine ganglion block) as effective treatments without systemic side effects.

Treatments to Avoid or Use with Caution:

• Diphenhydramine (Benadryl): Studies show it does not prevent akathisia from anti-dopaminergics nor improve migraine outcomes.
• IV Fluids: Routine use is not supported unless the patient shows signs of dehydration.
• Magnesium: Conflicting evidence with some studies showing no benefit or even harm.

Managing Refractory Migraines:

• Second-line treatments including additional doses of metoclopramide combined with NSAIDs or dihydroergotamine (DHE).
• Considering opioids as a last resort when other treatments fail.
